Aluminum source for electrolytic preparation of aluminum alloy, preparation method and method for preparing aluminum alloy using same

Abstract

The invention provides an aluminum source for electrolytic preparation of an aluminum-containing aluminum alloy. The aluminum source comprises complex salt which is formed by aluminum halide and alkali metal halides. The aluminum source comprises problems of easy water absorbing of aluminum halide at a normal temperature, easy sublimation at a high temperature, and high difficulty for controllingthe actual adding amount of the aluminum source. Furthermore the aluminum source has advantages of settling environment harm caused by sublimation of an aluminum halide aluminum source, settling a problem of aluminum hydroxide deposition generation caused by water absorbing of the aluminum halide aluminum source, and prolonging slag removal period of an electrolytic cell and service life of the electrolytic cell. The aluminum source is used for preparing the aluminum-containing alloy and can realize advantages of controlling the content of the aluminum element which enters electrolyte, furtherrealizing element proportion controllability of the aluminum-containing alloy, realizing high stability of element proportions in different batches of aluminum-containing alloy, and saving secondarymelting in preparing a workpiece through the aluminum-containing alloy material. Furthermore the aluminum source according to the invention can reduce sublimation of the aluminum element and reduces environment harm.
